Field-induced relaxation of crystal structure in dipole-glass phase of PMN — PT single crystal: X-ray study

Orientation dependence of piezoelectric properties of single domain 0.67Pb(Mn1/3Nb2/3)O3–0.33PbTiO3 crystals

“…In order to understand the origin of these high electromechanical properties, intensive research has been conducted on these crystals. [10][11][12][13][14][15][16][17][18] It is conceivable that the orientation dependence would play a key role in these multidomain systems, but one cannot evaluate it quantitatively because of the lack of a complete data set for the single domain state. Recently, we have successfully obtained such a complete data set for the PMN-33%PT by applying a bias field to maintain the unstable single domain configuration.…”

Dielectric Relaxation in Disordered Polar Dielectrics

“…For stepby-step change of relaxor properties the study of solid solutions of relaxors and conventional classic ferroelectrics is often used. In the literature the data concerned the study of binary solid solutions based on PMN, such as PMNPbTiO 3 [111][112][113][114][115][116][117], PMN-LaMg 2/3 Nb 1/3 O 3 [118], PMN-SrTiO 3 [119], most widely represented. The influence of small impurity concentrations in A and B positions on dielectric properties of PMN was studied as well [120].…”

Large Electro‐Optic Effect in La‐Doped 0.75Pb(Mg1/3Nb2/3)O3–0.25PbTiO3 Transparent Ceramic by Two‐Stage Sintering

“…The field‐induced phase transition occurred when an electric field was applied to overcome the energy barrier that prevented the material from developing into long‐range‐ordered (LRO) normal ferroelectric phase at a low temperature 5,6 . This electric field‐induced phase transition was usually characterized by an anomalous drop in dielectric permittivity when the electric field applied to the material was above a threshold field E th , which should reflect the energy barrier in the material 7–10 . No previous works have related the threshold field E th to the EO property of the material.…”

“…5,6 This electric field-induced phase transition was usually characterized by an anomalous drop in dielectric permittivity when the electric field applied to the material was above a threshold field E th , which should reflect the energy barrier in the material. [7][8][9][10] No previous works have related the threshold field E th to the EO property of the material. In our paper, we examined the threshold field E th and the domain configuration of our 3/75/25, and the large EO effect for La-doped PMN-PT ceramics was discussed.…”
